Description

Technical Field

[0001] The utility model relates to the technical field of sensor equipment, in particular to a temperature sensor installation structure for a diesel heater. Background Art

[0002] The fuel of a diesel engine is diesel. When the ambient temperature is below 5°C, the fluidity of diesel deteriorates, resulting in reduced spray quality, difficulty in starting the diesel engine, increased smoke emissions, and reduced engine service life. Therefore, a diesel heating component is required to heat the diesel at low temperatures. At present, the diesel heating component is assembled together using multiple structures, including a temperature sensor. However, after installation, the temperature sensor used in the diesel heating component often rotates between the connection socket and the external threaded connector, which can cause the sensor to fail to work properly in severe cases.

[0017] like Figure 1-3 As shown, a temperature sensor installation structure for a diesel heater includes a connecting socket 1, a ceramic mounting seat 2 and an external threaded connector 3. Several components are installed on the ceramic mounting seat 2. The insert on the ceramic mounting seat 2 passes through a through hole opened in the middle position of the connecting socket 1 and is placed in the upper half of the connecting socket 1.

[0018] A groove 4 is formed at the top of the external threaded connector 3, the ceramic mounting seat 2 is placed in the groove 4, and the bottom of the connecting socket 1 is wrapped around the outside of the ceramic mounting seat 2, and the bottom of the connecting socket 1 is clamped in the groove 4 at the top of the external threaded connector 3.

[0019] The bottom of the connection socket 1 is connected with an annular limiting ring 5, and the bottom of the limiting ring 5 is provided with a plurality of conical limiting teeth 6, and the angle between two adjacent limiting teeth 6 is 30°. An annular clamping groove 7 is provided on the bottom surface of the groove 4, and the clamping groove 7 is provided with limiting grooves 8 matching the number of the limiting teeth 6. The limiting ring 5 is placed in the clamping groove 7, and the limiting teeth 6 are inserted into the limiting grooves 8. The limiting teeth 6 are provided to prevent the connection socket 1 and the external thread connector 3 from rotating relative to each other when the connection socket 1 is installed, so as to prevent the connection socket 1 and the external thread connector 3 from being used normally.

[0020] Four latching protrusions 9 are provided on the inner wall of the groove 4, and the angle between two adjacent latching protrusions 9 is 90°. The side surface of the latching protrusion 9 is an inclined surface. Such a design facilitates the bottom of the connecting socket 1 to be inserted into the groove 4 at the top of the external threaded connector 3.

[0021] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
